[cisco-voip] PSTN Dialing

[Ramiz Sardar]

Sir,

I am working on voip setup. My topology you can see below:


User-------PBX1------R1----------------------R2-----PBX2---------PSTN

PBXs are connected with Routers and PSTN via E1 Pri whereas Routers R1 and
R2 are connect with each other through E1 link. Lets suppose site-1 has site
code 1000 and site-2 has code 2000 so when user dial 2000 and extension, it
connect to user of site-2. In old topology without voip, when user dial
2000, then 00 and then pstn number, it able to call users on pstn. Old
topology is :

User-------PBX1---------------------------------PBX2---------PSTN

But now through voip setup, can i do the same thing ? I think it should be
possible with configuration sample below:

R1
dial-peer voice 200000 voip
 destination-patern 200000
 session target ipv4:1.1.1.2

R2
dial-peer voice 200000 pots
 destination-patern 200000
 port 1/0:15
 forward-digit 2

I think using above configuration R2 will send 00 to PBX2 and an end-to-end
connection will be establish between user of site-1 and PBX2 and after that
user can dial whatever pstn number he wants. IF this will not work then  i
have to configure  a number of dial-peers for  pstn like 7 digits, 8 digits
and with destination-patern "T" etc.

Please help me out  regarding this issue. Am i thing in good way otherwise
purpose me solution Waiting........

Best Regards
Rameez
